Tool] vri/om t muy] concern.'

ing at Essen-on-the-Ruhr, Germany, have invented certain new and vusefulImprovements in Colui-Ovens, of which the following is a specification.

This invention relates to an improved arrangement of lines for suitablyheating tall eolie ovens. Sueh ovens have the detect that the lowerparts of the chambers are heated too much and the Lipper too little. Forobviating this detect in such ovens several places or Zones ofcombustion have heretofore been arranged one above another. Thearrangement ot the heating llues is then complicated, however, and theburners can be kept in order less readily.

According to my invention l obtain uniform heating of the walls ot' tallcoke ovens by beginning the heating lues of one wall not as heretoforeIat the same height. but at various heights. Thus whereas those places atwhich combustion takes place in one part of the heating Hues are locatedin the usual manner beside the lower parts 'ot the oven chamber, theplaces at which combustion takes place in the adjacent heating llues arelocated higher. In this arrangement an equalization of the temperaturetakes place, and uniform heating of thewalls of the chamber. isobtained. The tlues used for heating the upper parts of the oven mayhave a smaller cross-section down' to the height of the Hoor of the.chamber'. Conibustion then begins lower down; the development of flamesand severe heating can, however, begin vonly higher up. In this newarrangement the construction of the oven is considerably stronger thanother ovens of the type in question.

One illustrative embodiment of my invention is represented by way ofexample in the accompanying drawing, wherein:

Figure l is'a vertical longitudinal section taken through one wall of aheating llue. Fig. 2 is a vertical longitudinal section taken through011e wall of the heating line and showing a modification ot' theembodiment shown in Fig. l; Fig. 3 is a crosssection on line c-(Z ofFig. l; Fig. l is a cross-section on the line o o of Fig. 2; Fig. 5 is across-section on the line c-f of Fig. l; Fig. (3 is a cross-section onthe line g-z, otFig. l; and. F T is a cross-section on theline 2f Ze ofFig. Q. i

Referring to the drawing," the long heating flues l alternate with theshorter llues which begin higher up in the heating' wall l. In theright-hand half of Fig. l heating llues -L are `shown which begin at thelevel ot the hearth but have the full cross-section requisite for thedevelopment of llames only higlier up@vk 4 As is customary in ovens ofthis character, the gas and airs are admitted at the common lower levelof the tlues and ascend upwardly. Due to the fact that the longer andshorter tlues alternate in one embodiment or that the constriction's ofthe fines alternate inthe other embodiment, the heating will take placethroughout the whole et the oven at different heights, so that uniformheating of the walls ot' the chamber is obtained. y

ant'aware that changes can be made in the details of this invention andequivalents substituted therein, without departing from the spiritthereof as defined in the following claims.
